Defence Geospatial Information Working Group

DGIWG is the multi-national body responsible for geospatial standardization
for the defence organizations of member nations.

DGIWG has been established under a memorandum of understanding
between member nations, and addresses the requirements for these nations
to have access to compatible geospatial information for joint operations.
It supports the requirements of NATO and the other alliances
that its member nations participate in, including UN sanctioned peace
keeping. The requirements have been identified to address a specific set
of operational
scenarios.

The DGIWG geospatial standards are built upon the generic and abstract
standards for geographic information defined by the International Organization
for Standardization (ISO
TC/211). DGIWG makes use of the service specifications endorsed
by the Open Geospatial Consortium (OGC).

DGIWG defines information components for use in the development of product
specifications and application schemas for military geospatial data. DGIWG
also establishes service specifications, encoding formats and testing
methodologies to meet military geospatial intelligence requirements.

DGIWG also maintains an extensive Knowledge Base of documents related
to geospatial standardization, and historical documents such as
previous versions of the DGIWG
DIGEST exchange standard.
